Title: Furniture hinge on door outer face - is held by plates on furniture panel between door and panel
Inventor: PITTASCH WILLI
IPC: E05D5/04
Filed: 1975-06-03
Abstract: Furniture hinge for connecting a door has pref. a cylindrical pivoting bearing on the outer surface of the door when the door is closed. Hinge ensures secure fastening of the hinge components and is readily adjusted. Holding plate held on a wall within the furniture part is held at right angles to the door pivoting axis, and holds the end of the hinge bearing which is fastened on the door outside surface so that the bearing is aligned with the door edge at right angles to the door rotating plane. The holding plate reaches to the door outside surface through a gap between the door edge and the adjacent furniture wall. The hinge bearing can project over the whole of the door panel and both ends of this bearing are held by plates.

Title: Navigation system determining direction and distance of vehicle - e.g. helicopter, radiates interrogation pulses from which reference station determines direction
Inventor: BOEHM MANFRED DR ING
IPC: G01S13/76
Filed: 1975-06-09
Abstract: The navigation system is esp. applicable to a helicopter and, in any case, works w.r.t. a reference station. The vehicle concerned radiates interrogation pulses, from which the reference station determines direction to the vehicle and transmits it to the vehicle in a coded form. The vehicle derives from the answer the direction and determines from the signal its distance. The reference station can be board an aircraft moving continuously. It then continuously determines coordinates of the point at which the reference station lies and transmits them to the vehicle.

Title: Plastic container production process - moves head forming jaw and blowing mould to part and fit sealing cap
Inventor: NAUMANN WILLI
IPC: B65D1/02
Filed: 1975-06-21
Abstract: The process produces and seals a filled plastic container, using a seal formed from the same hose section as the container itself but separately connected to it. The head forming jaw is moved downwards and/or the blowing mould (17) is moved upwards, or the following tool is moved axially in relation to the container neck (12) before, during or after the shaping of the sealing cap (14). This parts the cap from the neck, and then joins it to the container (10) again. The forming jaw can perform a rotary movement as its fits or released the cap, and cap and neck can have raised or recessed outlines.

Title: Coin operated football and hockey game - has ball release free from jamming
Inventor: FRATZSCHER KURT
IPC: A63F7/22
Filed: 1975-07-24
Abstract: A ball release mechanism for a two-player, coin operated football or hockey game prevents incomplete release when the control is operated and released too quickly. The ball is supported behind a hinged flap (14) on an inclined plane (6) until the flap is released by the coin-controlled operation of the player. The inclined plane terminates at the flap, so that immediately on movement of the flap it falls down a shaft (15) under gravity and cannot "stick" in an intermediate position. Since there is no rolling, time is saved and no damage to the appts. can ensure as a result of very rapid action of moving parts.
Patent DE-2533391-A1 (DE)
Title: Bobbin yarn rests remover - with stripper engaging bobbin and removing successive axial portions of yarn rests adjacent bobbin tip
Inventor: BERTRAMS JOSEF
IPC: B65H73/00
Filed: 1975-07-25
Abstract: In the parent patent, device for removal of yarn rests from bobbins includes a stripper which corresponds with the bobbin dia. and which is movable axially of the bobbin, the movement between stripper and bobbin being intermittent and relative to one another. In this addn., each of the strippers is moved relative to the bobbin such that at first a portion of the wound yarn rest adjacent the bobbin tip is moved towards the tip and then successive adjacent portions are moved towards the tip. Yarn rests are wound extremely tightly on the bobbins and the present method of removal prevents breaking of the bobbins which in the past was a frequent occurrence.

Title: Unwinder for paper strip in belt-type filter with chamber - without using support or reinforced paper strip
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1975-10-15
Abstract: The unwinder uses the adhesive force between wet paper and a suitable worked surface to draw the paper strip with a filter cake on it from the filter chamber. Pref. the surface is in the form of a rubber-coated cylinder which is driven by a motor and which is provided with a guide roller beneath it. The paper strip may then be rewound by a winder. A scraper is mounted on top of the cylinder for removing the filter cake. When sufficient surface area of the cylinder is available and the paper strip is guided in such a way that it adheres over a large part of its surface area, the tensile force is sufficient to draw the wet paper strip with the filter cake on it out of the filter chamber. This eliminates formation of cracks in the paper strip.
